DRYING-ROOM.

Patented May 2, 1916.

To all whom it may concern:

Be it known that I, GRAY I; MORRISS, a

citizen of the United States, residing at- Ghicago, in the-county of Cook and State of Illinois, have invented certain new. and useful Improvements in Drying-Rooms, of which the following is a specification.

The present invention relates to a drying room arranged and adapted for use in drying fillers, stains, varnishes, enamels and kindred liquid and pigment products.

The object of the invention is to-provide means for establishing a circulation of air through the drying room, and for eductmg a certain portion of said circulated air dur ing the circulating process without the use of supplemental draft producing appliances for causing the eduction current.

The invention further consists in the features of construction and combinations of parts hereinafter described and claimed.

In the drawings: Figure 1 is a perspective of adrying room equipped according to the teachings of the present invention; Fig. 2 is a section showing the eduction means; and Fig. 3 is a view looking toward one side wall of said room.

The room is formedof an upper wall or ceiling 4:, a side wall5' and floor 6. The walls 4 and 5 are, as shown, each of hollow construction providing air chambers 7 and 8 respectively. The sidewalls, as will be seen from Fig. 3, ar'edivided into a series of compartments or lines by means! of uprights 9, the same being the usual and brat nary studdings of a building.

Located within the i terior o the room and extending parallel with, but spaced away from, the side wall5 arescreens 10, each of which terminates short of the ceiling and floor of the room, leaving an upper opening 11 and a lower opening 12. In the space intermediate the screens and side wall with which they are associated, are heating members 13 which may be of any suitable nature, and, as shown, consists of the ordinary steam coils supported by a suitable brace 14. A suitable air inlet duct 15 may be provided for admitting fresh air into the interior of the room.

Suspended from the ceiling and located approximately midway between the side Walls are cooling coils 16. The fresh air enters the spaces between the screens 10 and side walls with which they are associated,

.air, bafiles 17 are passes over the coils 13, becomes heated and rises in the spaces between the screens and their associated -slde walls, passes into the room through the openings 11, and encounters the cooling coil 16 by means of which it is cooled; and by such cooling action caused to descend into "the interior of the room and about the article or substance which is being treated. The air then passes through the opening 12, is reheated by the coils 13 and rises as before described. In order to more efliciently direct the flow of provided at the upper portion of the room.

The foregoing describes the arrangement for heating and cooling'the air and causing the circulation thereof. The main principle involved in this, however,'is old in the art, and no claim is made broadly thereto in the present invention. The gist of the present invention lies in the means for educting a portionof the circulated air which serves to increase the circulation of the air and allows of a steady changing of the air to prevent its becoming too heavily ladenwith fumes, and tocarry out this eduction with out the use of supplemental draft producing devices, using the heating means for causing the eduction flow. This eduction means in the construction shown,comprises a triangular shaped hood 18, which extends across the spacebetween each of thescreens 10 and the side walls'with whichsuch screens are associated. The hood,asshown,is formed with a closed top wall 19andjclosed side walls 20, but isopen at'its'bottom 21. Thehood "communicates-With the opening 22 in the inner side, wall23, and this in turn communicates with oneo'f' the spaces or'fiues 24: formed by the studdings 9 between the inner ,side wall 23 and the outer side wall 25. A port or opening 26 is provided at the top of the flue 24, out of which the educted air passes, as will be seen from Fig. 3. The hood 18 is of a size so that it extends between two adjacent of the studdings 9, and these hoods are interposed or positioned at periodical intervals in the spaces between the screens 10 and their associated side Walls, thus providing a certain and relative amount of eduction opening, so that a oer ,tainpercentage of the air which is being circulated is taken out from the room. This, as stated, serves to constantly change the air so as to prevent it from becommg too heavily laden with fumes. The eduction openings are located above the heating means, so that the acceleration of the air caused by its passing over the heating means gives to the air sufficient momentum to cause it to travel through the eduction passage, and hence no auxiliary draft producing means are necessary to cause the eduction flow.

Although the invention has been described with considerable particularity, it is understood that changes may be made in the structure described without departing from the spirit of the invention, provided the structure produced is maintained within the confines of the appended claims.

I claim:

1. In a drying room, in combination with inclosing walls, a ventilating fiue located behind one of the inclosing walls, a screen located in front of said wall and open at the top and bottom for communication with the interior of the drying room, heating means located behind the screen, means adapted to establish communication between the space intermediate the wall and screen and said ventilating fiue to educt a portion of the circulated air, said means opening to said space above the heating means, and means for admitting fresh air, substantially as described.

2. In a drying room, in combination with inclosing walls, a ventilating flue located behind one of the inclosing walls, a screen located in front of said Wall and open at the top and bottom for communication with the interior of the drying room, heating means located behind the screen, a deflecting member above the heating means extending across the space intermediate the inclosing wall and screen and in communication with the ventilating flue for diverting a portion of the circulated air into said ventilating flue,

. and means for admitting fresh air, substantially as described.

3. In a drying room, in combination with inclosing walls, a screen located in front of one of said walls and open at the top and bottom for communication With the interior of the drying room, heating means located between the screen and wall, means located above the heating means for educting a portion of the air rising from said heating means, and means for admitting fresh air, substantially as described.

4. In a drying room, in combination with inclosing walls, a screen located in front of one of said walls and open at the top and bottom for communication with the interior of the drying room, a series of eduction passages in the space between said wall and screen, and located above said heating means, said passages being located at periodical points to extract a portion of the heated air rising from said heating means, and means for admitting fresh air, substantially as described.

5. In a drying room, in combination With inclosing walls, a screen located in front of one of said walls and open at the top and bottom for communication with the interior of the drying room, heating means located between said screen and Wall, an eduction passage communicating with the space between the screen and wall and located above the heating means, and a deflector for di verting a portion of the air rising from said heating means into said eductlon pas sage, substantially as described.

6. In a drying room, in combination with inclosing walls, a ventilating flue located behind one of the inclosing walls, a screen located in front of said Wall and open at the top and bottom for communication with the interior of the drying room, heating means located behind the screen and below the intake for the ventilating flue, and a hood adjacent to the intake and projecting into the space intermediate the wall and the screen at a point above the heating means for diverting a portion of the heated air into the ventilating flue, substantially as described.
